support request - PCM1803A

Hi,
 
My question concerns the PCM1803a :
The delta-sigma modulator is 1-bit or n-bit ?
What is the order of the modulator ?
Can we see some spikes (idle tone) in the noise floor ?
 
 
For the PCM1802, I find this in the datasheet :
The high-order delta-sigma modulation randomizes the modulator outputs and reduces the idle tone level.
 
 
 
The delta-sigma modulator
1-bit
?
The order of the modulator
5
?
Idle tone
reduces level by The high-order delta-sigma modulation
?
 
Best regards,
